To all whom it concern.-

whicllnre similar in their exp naive properties to existing standard grades of lh'namite. 'l'hg 'commerciul explosives in which it has heretofme been Propo ed to ineorponte xaid to full in two main claw. In one chou IN compositions in which a small percentage of trimtxotolllol is used in eon motion with relatively large "percentages 0' nitroglycerin for the of producing the sorcalled lowtlymlmite.

In explosive compositions of the other elm, low percentages-oi trlmtrotoiuol are mod on. relatively h W828 of explosive salts having 'n ql ig 1 oxygen content euch as 'iunmoninm nitrate, ammonium perehlggte pqtassuun ehloi nte or. rohlomte,

Thirdly, they are woolly or duty and mnmqueutly dangerous; lo, and unit gieuic to manufacture.
